Abstract:

In order to achieve the fine-grained access control and the anonymity of the user access to data in the Internet of Things, an attribute-based access control model is proposed and realized by using the bilinear map. In this scheme, users request data access to the sensor node based on their attributes certificates and the sensor node determines whether to allow access according to the threshold principle. This scheme effectively realizes the flexible fine-graind access control and anonymous access to data. The number of interactions between users and sensor nodes is minimized and the computation of sensor nodes is reduced to one public key encryption. Analysis shows that the scheme has the advantages over the current access control mechanisms of better scalability and lower cost in communication and computation and can adapt to access control requirement of perceptive layer of the Internet of Things.

Key words: the Internet of Things, wireless sensor networks, access control, anonymity
